PEDESTAL FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 312,079, dated February10, 1885.

Application filed October :22, 1884.

T aZZ whom it may concern.-

Be it known that we, BARNAD BRIODY and GEORGE W. MoHALE, of Detroit,county of Wayne, State of Michigan, have invented a new and usefulImprovement in Pedestals for Railway-Cars; and we do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform a part of this specification.

Our invention consists of the combinations of devices and applianceshereinafter specified,and more particularly pointed out in the claims.

Our invention has for its object certain new and useful improvements inpedestals for railway-cars, such as are employed to support the axles ofthe trucks, and in which their boxes are located.

It is a well known fact among railroad men that the working of the boxesin the pedestals causes the pedestals to wear unevenly,

and to such an extent that in a few months,at most, for cars in ordinaryuse, the pedestals must be taken off and replaced by new ones, and theold ones, in consequence of the wear, have heretofore been broken up,necessitating a considerable waste and expense, the operation ofreplacing the pedestals taking a considerable amount of time. This wearcomes upon the sides of the pedestals adjacent to the boxes. This mayresult from the ordinary 3 5 jolting of the car, and the consequentswaying of the'boxes in the pedestals, which occurs, also, especially ingoing around curves, and when the brakes are applied,forcing the boxesagainst one side of the pedestal,in consequence 40 of which theoil-boxes also wear, so that they tip and wear the brasses upon thejournals, necessitating the renewal of the brasses as well as thepedestals and oil-boxes.

It is the object of our invention to remedy these difficulties by themeans hereinafter described and claimed.

In the drawings, Figure 1 is a vertical section of a pedestal with itsoil-box,illustrating our invention, showing parts in elevation.

Fig. 2 is an inverted plan view. Fig. 8 is a modification.

(No model.)

We carry out our invention as follows: A represents the pedestals, whichmay be constructed in the usual manner, except that they are grooved toreceive our improved wearing-plates B. O is the ordinary oil-box; D, theordinary brass of the journal bearing.

E is the usual equalizer. F is the stretclr er or stringer whichsupports the oil-box in the pedestal. In the construction of new 50pedestals they are cast to receive the wearing-plates 13 upon the sidesof the boxes. These wearing-plates are preferably four in number, asshown more fully in Fig. 2, there being two upon a side. These platesare preferably made angular, as shown, the lugs c of the oil-boxespresenting awearing-face at right angles to the sides of said boxes. Byconstructing the wearing-plates angular they receive the wear of thelugs as well as of the sides of the boxes.

We do not of course confine ourselves to the formation of new pedestalswith our improved wearing-plates, as old pedestals which have been wornand become unfit for use, as heretofore employed, may have their wornedges planed down and straightened to receive our improvedwearingplates, and when these plates have been thus applied the oil-boxand brasses are straightened up and trued again, and in this manner theold pedestals become as good as new, effecting a large saving. Thesewearing-plates may be secured in place in any suitable manner, as we donot confine ourselves to any particular method. We find it mostconvenient to construct them so as to rest at their lower ends upon thestretcher F, when in place, which will hold them in position when theyare to be applied or renewed. By disconnecting the stretcher-bar theymay be removed or inserted readily and the stretcher be again secured inplace in a very little time.

As shown in Fig. 3, the wearing-plates may be secured in place by acountersunk screw, 5 as shown at b, on the inside adjacent to the box,or the wearing-plate may be provided with a flange, b, so that it may besecured by a bolt, b upon the outside of the pedestal.

The wearing-plate, being constructed in any suitable shape, may havevarious methods of fastenings.

It will be more convenient for repair purposes to secure thewearing-plates in place by means of screws; but in new pedestals weprefer to secure them by means of the stretcher.

By the employment of our improved pedestals the brasses are preventedfrom wearing thinner upon one end than the other, the oilbox may be kepttrue, and a great saving effected, as the same pedestals may be employedfor an indefinite length of time, the only thing required being to renewthe wearing-plates occasionally, as circumstances may demand, which maybe'done economically and readily.

The wearing-plates may be prevented from working up in any desiredwayas, for in-' stance, the pedestal may be cut away on its lower endsufiiciently to receive a lug, b upon the plate.

What we claimis- 1. The combination, with the pedestal A and box 0,formed with lugs c, of the removable wearing-plates B, fitting withinrecesses in said pedestal, and formed angular, as

shown, to receive the wear of said lugs as well as the sides of saidbox, substantially as described.

2. The combination, with the pedestal A and box 0, of the removablewearing plates B, formed at their lower ends with lugs b fitting inrecesses in the pedestal, substantially as described.

3. The combination, with the recessed pedestal A and box 0, formedwithlugs c, of the removable wearing-plates B, fitting within the recessedpedestal, and formed angular, as shown, to receive the wear of the sidesof said box and'of lugs, and provided at their lower ends with lugs h tofit in recesses in the pedestal, substantially as described.

In testimony whereof we sign this specifio cation in the presence of twowitnesses.
